cleaning black tiles

[chilli74]

need help, i am having an absolute nightmare trying to clean newly laid tiles in my bathroom, everytime i wash them they dont really look clean and all i get coming off the tiles is black having washed the tiles several times now.
the tiles are black porcelain riven tiles in a matt finish, also i have used black grout.
is there anyone who can provide some advice or a solution to my battle with these damn tiles!!!

How long has it been since you grouted. What grout and explain your grouting methods

 

[chilli74]

grouted next day after laying floor used a wide joint grout powder mix i think it was Larsen brand

Look you will have to explain in more detail so we can feel what is going wrong.
Have you grouted and washed off then washed again and again before the grout is dry. If so all you are doing is washing the grout out and over wetting the floor.

For these dark grouts I use Mapei, you dont get the problem.

grouted then washed off before grout had dried (twice) and then washed then tiles the next evening again
i am waiting to seal the grout with protector have been putting it off as everytime i wash all i get is black coming off the tiles
ps the grout had fully dried when i washed them the next day

Have you tried buffing off.

matt porcelain,,interesting did you seal these tiles?

 

[chilli74]

sorry am a diyer what do u mean by 'buffing off'
i was told that they did not need to be sealed

 

[Gazzer]

Buffing, rubbing with a dry cloth ?

 

[kilty55]

black grout can be a real pain to work with,it does seem to take a while longer to remove the haze once dry,buff the tiles once dry with a dry cloth to properly remove the haze...leave then wash again and you may see a difference

have you tried sponging them and changing the water very frequently?

 

[Gazzer]

Use the porosity test on this page to see if they need sealing

went over the top with a hoover to clean some of the dust but will try buffing tomorrow

PS black is an right royal *** to work with and i hope never to encounter this hell spawn after this
